“…Current commercially available OPM devices are nothing more than a simplified version of optical spectrum analyzers [114]. These devices are capable of monitoring a few parameters such as wavelengths of WDM channels, total optical power, and out-of-band OSNR, and are normally referred to as optical channel monitors (OCM).…”

Optical Performance Monitoring (OPM) is the estimation and acquisition of different physical parameters of transmitted signals and various components of an optical network. OPM functionalities are indispensable in ensuring robust network operation and plays a key role in enabling flexibility and improve overall network efficiency. We review the development of various OPM techniques for direct-detection systems and digital coherent systems and discuss future OPM challenges in flexible and elastic optical networks.

“…Moreover, they are required to handle multichannel WDM links at low implementation cost. There are many OPM methods [10][11][12][13]. However, the techniques are usually based on direct measurement of optical parameters such as OSNR [14][15][16], pilot tones [17], Q-factor measurement [18,19], in/out-of-service BER measurement/estimation [20][21][22], subcarrier multiplexing [23], data correlation [24], non-linear detection [25].…”

A key feature of Carrier Ethernet networks is its operation and management framework. The link state, in this context, is simply determined by the detection (or absence for a given period) of continuity check message (CCM) at the receiver end of a management end point. However, cross-layer information can be inexpensively gained by looking into the loss patterns of these CCM frames, especially when Carrier Ethernet is operating directly over wavelengths (Layer-1) from transparent optical links or networks. This paper experimentally demonstrates a case for optical signalto-noise and optical signal-to-interference estimation from monitoring standard CCM frame loss frame rate. Moreover, the loss pattern signatures of such physical-layer impairments may give in-depth link state information for fault and performance management as it may give valuable clues about the dominant impairing phenomena.
